BOTTLE DECAPPER.

Application filed March 1, 1927. Serial No. 171,786.

This invention relates to improvement in bottle decappers, and particularly to devices scribed and particularly recited in the claim.

In the accompanying drawings:

Fig. 1 is a face view of a bottle decapper constructed in accordance with my invention;

Fig. 2 is a side view of the same;

Fig. 3 is a top View of the same;

Fig. 4 is a vertical sectional View with the neck of the bottle shown in broken lines in position for being decapped.

In carrying out my invention, I form a single casting, preferably of iron, comprising a back-plate 5 formed with screw-holes 6, by which it may be attached to a wall or other support. Projecting forward from' this plate and in a plane upwardly therefrom is a semicircular frame 7, comprising a lower lip 8 and an upper flange 9, said lip and flange being arranged in parallel planes, the inn-er wall 10 of the frame 7 being curved corresponding to the general curve of bottle caps.

A bottle to be decapped is placed in the device, as shown in Fig. 4 of the drawings, so that the under edge of the cap rests upon the lip 8, while the flange 9 extends over the top of the cap. By inclining the frame, as shown, it permits of the insertion of a capped bottle into the device without having the bottle come into contact with the 'sup port. The device operatesin the usual manner of decapping devices, that is, after the cap is inserted, the bottle is further tilted so that the lip 8, engaging with the lower edge of the cap, holds it against movement, while the bottle is pulled, away from the cap. OW-

ing to the semicircular form of the frame, and the parallelism of the lip and cap, the cap, after the bottle has been pulled away, will remain in the frame in convenientposition to be picked up, and on account of the engagement of the lip 8 and the flange 9 around substantially half the circumference of the cap, prevents the cap from being so mutilated that it cannot be replaced on the bottle if desired. These devices are readily 60 formed, from a single'casting and may be finished in any desired manner and can, consequently, be produced for very low cost for manufacture, and, due to the form of the de vice, the bottle can be decapped by turning 66 it either to the right or the left, or straight outward.

I claim:

A bottle decapper, comprising a base and a frame formed integral therewith and pro jecting forwardly and upwardlytherefrom, said frame formed with a semi-circularlip and with a semicircular flange, said lip and flange being arranged in parallel planes, the

wall of the frame between the flange and lip being curved substantially as described.

In testimony whereof, I have signed this specification.
